The Vauxhall Astra GTC line up has been extended to include a more powerful 197bhp 1.6-lire direct injection petrol engine, which will be available with the sporty three-door. The engine has been adopted from the Cascada convertible.
Developing 197bhp and 300Nm of torque, the new four-cylinder engine option makes the GTC the most powerful non-VXR model in the Astra range – with power increasing by up to 30 per cent over the previous 1.6-litre turbo motor. The sprint from 0-60mph is dealt with in 7.3 seconds and top speed is 143mph.
As well as boosting performance, Vauxhall has also managed to improve economy compared with the outgoing engine, too. The manufacturer claims the GTC will return 51mpg and emit 154g/km of CO2 – a 13 per cent improvement in efficiency. The new engine also uses a twin balancer shaft for smoother running, along with a host of sound engineering improvements to reduce noise, vibration and harshness (NVH).
Vauxhall has also introduced an Intellink infotainment system across the Astra GTC range, priced from £855. The package features satellite navigation, Bluetooth, voice control and a picture viewer via a high-res seven-inch touchscreen.
Prices start from £20,995 for the new 197bhp 1.6-litre Astra GTC. Order books are currently open with first deliveries expected in the spring.
